(120, 183, 453)-Net over F₄ — Digital

Digital (120, 183, 453)-net over F₄, using

Gilbertâ€“VarÅ¡amov bound [i]

(120, 183, 14151)-Net in Base 4 — Upper bound on s

There is no (120, 183, 14152)-net in base 4, because

1 times m-reduction [i] would yield (120, 182, 14152)-net in base 4, but
- the generalized Rao bound for nets shows that 4^mÂ â‰¥ 37 596869 599308 442073 380056 860824 901028 047292 332343 959025 633654 009094 916689 561934 412173 687617 252759 682026 787176 > 4¹⁸² [i]
